"Fractional-Order Investigation of Diffusion Equations via Analytical Approach", Frontiers in Physics, Vol. 8.2296-424Xhttp://hdl.handle.net/20.500.12416/5485This research article is mainly concerned with the analytical solution of diffusion equations within a Caputo fractional-order derivative. The motivation and novelty behind the present work are the application of a sophisticated and straight forward procedure to solve diffusion equations containing a derivative of a fractional-order. The solutions of some illustrative examples are calculated to confirm the closed contact between the actual and the approximate solutions of the targeted problems. Through analysis it is shown that the proposed solution has a higher rate of convergence and provides a closed-form solution. The small number of calculations is the main advantage of the proposed method. Due to a comfortable and straight forward implementation, the suggested method can be utilized to nonlinear fractional-order problems in various applied science branches. It can be extended to solve other physical problems of fractional-order in multiple areas of applied sciences. © Copyright © 2021 Liu, Khan, Mustafa, Mou and Baleanu.eninfo:eu-repo/semantics/openAccessCaputo OperatorDiffusion EquationsFractional Differential EquationIterative Shehu Transform MethodMittag-Leffler FunctionArticle810.3389/fphy.2020.568554
